Last Wednesday was apparently a freeze day for the Gecko 1.9 rendering engine (which will appear in Firefox 3). A laundry list of new features have been added, as can be seen from the most recent nightly build report. Full page zoom is one of the biggest new features coming, though it has not yet been enabled via the GUI (you have to download a separate test extension to play around with it).

One particularly nasty regression (bug 390451) lurks in the nightly builds, so I'm not planning on switching my base install to this alpha. But it looks like it won't be much longer before we can enjoy some new Firefox features.
